COIN-CONTROLLED STRENGTH-TESTING MACHINE.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed May 28,1903. Serial No. 159,078.

To all who/1t .it Tim/y concern:

Be it known that I, WILLIAM WV. ROSEN- FInLD, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Coin-Controlled Strength- Testing Machines, of which the following is a specification.

My invention relates to a coin-controlled machine adapted for testing the human strength in which a common instrumentality is actuated both by an upward-pulling position of the body and also by an approaching movement of the hands operating separate devices. These movements are independent of one another, and each separately indicates on a common instrumentality the force employed.

In the operation of my improved testingmachine and when either hand-moved instrumentality is brought into play after a coin of predetermined denomination has been inserted the force applied moves a rod and head downward against the expansive action of a spring. This head carries an arm adapted to bear upon the coin inserted in the machine, which when moved down carries with it a slidable block actuating a rack and pinion, the pinionshaft, and index to show the force applied. A friction-clutch device is employed to hold these latter devices in their extreme position until released after the return of the firstnamed means to their normal position, and I provide suitable devices adapted to prevent the fraudulent use or repeating with the machine with a single inserted coin, all of which are hereinafter more particularly set forth.

' In the drawings, Figure l is a front elevation of my improved coin-controlled strengthtesting machine. Fig. 2 is a side elevation, a part of the base being broken away. Fig. 3 is an elevation of the case and internal mechanism with the dial, front plate, and handles removed and the shafts of the handles and index in section and one guide-rod broken away. Fig. 4 is aside elevation with part of the case and certain other parts in section. Fig. 5 is a vertical section and elevation of the coin receiving and engaging devices. Fig. 6 is a sectional plan at .fr a' of Fig. 4, and Fig. 7 is a central elevation at the back with the rear plate removed.

c represen ts the hollow base of the machine, with which is made a platform o to stand upon. At the back of the hollow base rises a standard b, the main case c being mounted upon the standard b and provided with an auxthe case.

iliary or back case c. At the forward portion of the hollow base there is an auxiliary standard Z1.

d represents the dial upon the face of the case c at the upper end, 2 the index or hand to indicate the force applied, and 3 represents the coin-slot.

A hand-bar CZ is upon the upper end of a rod g, that passes down through the auxiliary standard o. In the hollow base there is a lever g', pivoted at 4: to said base. This lever, as seen in Fig. 2, is slotted at the left-hand end to receive a pin which passes through the rod `fand-is the means for connecting said rod g and the lever g', the pin moving in the slot with the change of position ofthe parts.

The right-hand end of the lever g is provided with an opening to receive the main rod L, which passes through it, as well as through the hollow base a, and in the end of the rod L is a pin coming below the end of the lever g. ef represent the hand-levers. These are outside of the case c and at opposite sides. They are connected to shafts e f', which pass through lugs at the sides of the case and the ends of which shafts pass inside of the auxiliary or back case c and terminate in arms The main rod L passes up into the auxiliary or back case c' and through limiting-stops on the back of the case c. A helical spring 7U, with washers at the respective ends of the spring, surrounds the main rod L between these stops 5 6, and there is a pin 7b2 through the rod /t beneath the stop 6 and above the adjacent washer. At the upper end of the rod L is a head r1, having a forward-extending arm t" passing through a mortise in Ithe back of the main case and which head is also provided with side extensions slidable against the ways a2 on the back of the case c. Fig. 7 shows the normal position of the hand-lever shafts and their arms czfz, in which the free ends of the arms, which lap one another, are directly over the center of the head t' and come below a lug 19 of the casec, which by holding down the arms e2f2 preventaswinging or overloalancing movement of the handlevers ef.

I provide guide-rods 7 8, occupying a plane parallel to the front of the case. The upper ends of these rods are secured to the top of the case and their lower ends to a bracket 9, secured to and projecting from one side of These rods 7 8 become guides for the slida'ble block 7c. This block is of peculiar shape, (see Figs. 3, 4, 5, and 6)---that is to say, it is made with portions through which the rods 7 8 pass. It is provided with a coin-slide 7c', notched at its lower end and formed between parallel ribs. (See Fig. 6.) There is a block 1() adjacentto the upper ends of the guide rods 7 8 and through which they pass, which block is held to said guiderods by a screw and a tension-spring 11 at its upper end is hooked onto this screw or tapbolt, and the lower end of this spring 11 is secured to a clamping-screw 12, which passes through the slidable block 7c, the said screw 12 firmly connecting the rack-rod l to the slidable block 7c. This rack-rod is preferably round, and the teeth forming the rack are cut into one side of the same, said rack-rod being guided in the block 10.

The shaft m passes through the upper end of the case c, its rear end having a bearing in the back of the case and its forward end a bearing at the center of the dial. The forward end of the shaft carries the index 2, and upon this shaft m is a pinion m', meshing with the teeth of the rack-rod Z, so that by the up-and-down movement of the rack-rod the pinion m', shaft fm., and index 2 are rotated. On the shaft m and at the back portion is a hub m2, and pivoted to a boss 13 upon the back of the case is an arm n, said arm moving on the pivot 14, secured to the boss 13. The arm n is made with a friction-ring n surrounding the shaft fm/ and adapted to bear upon the face of the hub m2 of the shaft m. To this arm n at the lower end is connected a push release-pin n2, the same being pivotally connected at one end to said arm and extending through the front of the case and slightly beyond the same, so as to be manipulated by hand. A spring 15 is located between the front of the case and the arm n, one end ofthe spring being connected to an eyelug of the case and the other end to an eyelug of said arm, the function of the spring beingI to draw the lower end of the arm toward the front case and apply friction between the friction-ring a' and the hub m2 to prevent the shaft m and the parts associated therewith from being moved.

I provide a follower o in the form of a block having apertures through which pass the rods 7 and 8 and having an inclined part generally parallel with the inclined coinway part of the slidable block 7c. The end of this inclined part is notched, and on the under side there are lugs 16 and at one side an adjusting-screw 17, Figs. 5, 6. The notched portions of this inclined follower and the inclined part of the slidable block 7c receive the free end of the arm c", the face of which is inclined so as to be parallel with the inclined portion of the block c., and it is apparent that it is possible with the vertical movement of the rod L, either by means of the hand-levers @for the hand-bar CZ', for the free end of the a-rm z" to pass through these notches of the slidable block /r and vthe follower o, providing there is no intervening coin. This follower 0 is provided with a vertical face o', hereinafter more particularly described. On the left-hand side of the case (see Fig. 3) there is a bracket 18, providing a bearing for the pivoted rack fr, which hangs normall y by gravity from its connection with said bracket and which rack is provided with an arm 7 and which arm fr extends across over the free end of the arm c". l

The operation of the machine is substantially as follows: The coin is inserted into the machine through the coin-slot 3. This coin may be a nickel or a cent. In either case the slideway 7c between the side ribs of the slidable block 7c is wide enough for the coin. 1f a nickel, the coin stops against the side lugs 16. If a cent, the same stops against the screw 17 and one lug 16. If now a person testing his strength grasps the hand-bar df, standing on the platform a', and pulls upward, the lever g is swung on its pivot 4 and the main rod /L is drawn down against the tension of the spring L'. The spring is compressed, and in drawing down the rod the headvl and arm z" are simultaneously moved. The arm a" comes against the coin with the initial movement of the parts, and through the intervention of the coin the arm c" moves downward the slidable block 70, the rack-rod Z straining the tension-spring 11, turning the pinion m', the shaft mf, and the index 2 so long as the downward movement of the rod L continues.

It will be noticed that the arm r' of the rack fr extends above the free end of the arm z" and in the position Figs. 4 and 5 substantially rests on this arm, so that the rack ff' is held away from the lug k2 on the side of the slidable block 7c, but when this arm fz," moves down the said rack hangs by gravity, and as the lug 702 moves downward with the slidable block f: the same runs over the surface of the teeth of the rack fr, and when the limit of this movement is reached the teeth of the rack close over the lug preparatory to holding the same in position. Simultaneous with this movement the grip of the pivoted arm n and friction-ring n againstthe hubm2 of the index-shaftis in evidence to hold the parts in the position reached by the pressure or the force applied by the person testing his strength. The moment that this pressure is released the spring' /L acts to return the rod L, the lever g', the rod g, the hand-bar c?, the. head fr; upon said rod, and the arm c" to their normal or initial position. As

vthe arm fel starts upward the coin is released whilethe arm c" is moving upward but before this arm e" reaches its normal position it engages the arm r of the rack and swings the rack free from the lug le?, so that were it not for the friction-grip ofV the arm fn, and the parts associated therewith the spring ll would at once return the slidable block it' to its original or initial position preparatory to a repetition of the aforesaid movements. In connection with this movement the hand-levers ef and the partsassociated therewith to and including the arms f2 are not moved at all, because the free ends of these arms a2 f2 come above the head z', (see Fig.` 7,) and they are not affected by the downward movement of the head 't' and rod If a person testing his strength operates the hand-levers e f, the free ends of the arms eff? are brought with force on the top of the head @l to force down the rod /t against the expansion of the spring t', and in doing this the arm t" is after the insertion of the proper coin brought against the coin, so as to force down the slidable block 7c and repeat the operations hereinbefore described and indicate a force applied upon the dial. 1n this latter movement the arm It at its lower end moves freely through the eye at the end of the lever g', so that this lever, the rod g, or the hand-bar lf are not in any sense affected or moved. The relation of the respective forces applied as between the handbar d and the hand-leversef and indicated on the scale is such that the force indicated by the hand-bar d can be read as indicated, but the indication produced by the operation of the hand-levers c f should be divided in two to arrive at substantially the exact force applied.

Vith either operation and after the release of the hand-bar Z or the hand-levers ef the push release-pin a2 is to be forced into the case to overcome the tension of the spring l5. swing the arm n. and release the frictional hold of the ring n and hub m2. This frees the shaft m and permits the tension-spring' ll to act to draw upward the slidable block and rack t, and so rotate the pinion m and shaft m, returning the index 2 to the zeromark ready to repeat the operations.

It willbe noticed that the follower 0 is provided with a vertical face o and a side lug 02, and this face o moves in a plane parallel with the plane of the front of the case and in its limited descent passes across the coin aperture or slot 3 and in the movement of the parts will prevent the insertion of another coin, because this follower 0 only descends until the side lug 02 strikes the corner-shoulder of the bracket 18, which assists its movement and suspends the said follower upon the guide-rods 7 and 8, with its vertical face 0 closing the coin-slot and preventing the insei-tion of another coin until all the parts are raised to their normal position, the latter part of the movement of which raises the follower to the position shown in Fig. 5.

The main function of the rack fr, pivoted to the bracket 18 and its arm r, is to prevent fraudulent repetition or beating of the machine, as it will be noticed from the drawings and the foregoing description that this rack engaging the lug 7a2 positively holds down the slidable block at the position reached until almost the end of the return movement of the arm t". Should an attempt be made, as an illustration, by some one engaging the handbar d to test their strength immediately following the test of some one operating the hand-levers ef, or vice versa, or should some one desire to test his strength several times in succession it is necessary in all cases that an effort be made with the movement of the parts to maintain the coin in the coinwayA hold the coin between the same and the end of the'arm t. Under these circumstances were it not for the rack fr and the lug on the side of the slidable block a fraudulent repetition or beating of the machine might be effected; but it will be apparent that the presence of these devices in the machine makes this action impossible, because the moment that the arm e" passes down below the gravity position of the arm fr' the said rack fr is effective for engaging the lug to hold the slidable block f: to whatever position the eXtreme downward movement has carried it.
